Gas-driven refrigeration series

Gas Heat Pump with integrated heat exchanger

Micro Cogeneration Unit

Yanmar has a global workforce of over 15,000 and a sales network operating in more than 130 countries. We design and manufacture diesel engines, accessories and equipment for a wide range of applications in pleasure craft and commercial marine vessels, for industrial use, agricultural machinery, construction equipment as well as gas engines for cogeneration and gas heat pump systems. The company has pioneered clean emissions technology and sustainable energy systems. In Europe, Yanmar employs around 600 people and generates annual sales of approximately Euro 800 million.

We are proud to have KKU Concept, a full subsidiary of Eschenfelder KKU in Marl, as our partner and German distributor for Yanmar Gas Heat Pumps. Their first responsibility is the introduction of the new GHP product line in Germany. Eschenfelder KKU is an established, well-known HVAC (Heating, Ventilation, and Air-Conditioning) company in the German market. Eschenfelder KKU has been engineering, installing and servicing gas heat pumps for many years and is recognised as a trustful and reliable partner to provide solutions for their customers.

Gas-driven refrigeration series

Yanmar Europe is the first to introduce a gas-driven refrigeration unit to the European market. The most striking user advantages of the new gas-driven refrigeration series are its very limited energy consumption, high output, compact design and heat reclaim. Having pioneered clean emissions technology and sustainable energy systems for many decades, Yanmar now brings a new refrigeration series to market offering customers a choice to use natural gas as a main energy source for refrigeration.

Made in Japan, the gas driven refrigeration is developed in Europe and fully dedicated to European requirements. The series comes in different units with a powerful cooling capacity between 26-53kW at a limited electrical energy input as low as 0.9-1.7kW. Its cooling range is between 0-10 C. Yanmar’s new, compact gas-driven series is easy to install and delivers the same capacity as bigger, more expensive electrical installations, while occupying far less space. Since it can be installed outdoors without the need for a technical room, it also saves valuable indoor space.

Gas-driven refrigeration use less than one-tenth of electrical power input when compared to electricity-driven refrigeration. Consequently, the consumption of primary energy is highly reduced, which is a true environmental benefit. There are economical benefits too. One is that natural gas is a less expensive energy source than electricity. The other is that variable capacity control depending on situational demand or need leads to optimal cost management and highly efficient operation.

A big plus for the new gas-driven refrigeration is the ability to reclaim heat from the engine. The waste heat that is produced ‘free of charge’ can be efficiently used for heating, defrosting or for domestic hot water application. Again, this brings both economical and environmental benefits.

A remote 24/7 monitoring system observes operating conditions via the internet and provides direct notification to the service engineer when action is needed. Another operational benefit is that the units operate at very competitive, low noise levels. Finally, customers can simply upgrade the refrigeration system without the need for a new electrical transformer.

Gas Heat Pump with integrated heat exchanger

Yanmar’s clean gas heat pump (GHP) is entirely based on a new concept with a built-in reversible chiller, unique to Yanmar. It is an environmental-friendly alternative to already existing air-to-air GHPs with indoor units and air-to-water GHPs with hydro modules. By incorporating a heat exchanger into the GHP unit, the Yanmar GHP chiller is self-contained, allowing for direct hydronic connection to the unit, saving installation space and resources.

The key product features include:

• water chilling and heating modes

• high efficiency

• direct water system connection to the unit

• hot water recovery for sanitary use

With one of the longest maintenance intervals in the industry, high quality and reliability, the Yanmar GHP chiller is used in a wide variety of commercial applications from comfort air conditioning to the replacement of boilers and other systems in many industrial and public sectors. Yanmar first aims for the 71 kW model while the conventional GHP will be available in 45, 56, 71 and 85 kW.

Micro Cogeneration Unit

All models are powered by a Yanmar gas engine, to run on natural gas, propane or biogas, depending on the model. The engine drives a highly efficient and compact generator that provides electrical power output through an inverter, assuring easy grid connection and stable power output. Heat is captured through a heat exchanger, heating water for instant use or tank storage. Depending on local regulations, excess electricity can be sold back to the grid, enhancing the system’s payback.

Each compact package under a low noise all-weather canopy has a STANDARD MAINTENANCE INTERVAL OF 10,000 HOURS, one of the longest in the industry. This makes it possible to run continuously for 13.7 months before the first minor routine servicing is required. Other features are partial load operation, an advanced system controller, electrical or heat demand operation and a remote monitoring system.

The largest model, the CP25WE at 25 kWe, can be configured with up to eight units running in parallel, creating an output of up to 200 kW. Smaller models also can be linked, to work in two or three parallel formations.

The target markets for the Yanmar units are mainly commercial applications like hotels, restaurants, nursing homes, agricultural and horticultural facilities, swimming pools and health spa’s, but also larger private residences.
